Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a roller-type atomizer comprising a paint roller rotatably supported at the tip of a handle via a support rod, and in particular a roller-type atomizer comprising a paint roller rotatably supported at the tip of a handle via a support rod. This invention relates to a roller-type atomizer that can be used by switching between a rotatable state and a non-rotatably locked state depending on usage conditions.

(Prior art and its problems) The roller-type atomizer as described above is similar to the usual painting method in which a painting roller is rolled over the surface to be painted, and the same as in the case of painting using a brush. It has the characteristic that it can be used for painting by rubbing the roller on the surface to be coated without rolling it, but in all conventional roller-type coating machines of this type, the coating roller is attached to a lock lever. The structure is such that a large bending force is applied to the lock lever when used in a fixed position.
There was a risk that the lock lever would be deformed when the fixed roller was forced to slide against the surface to be coated.

(Means for Solving the Problems) The present invention proposes a roller-type paint device that can solve the conventional problems as described above. In addition, the roller-type paint device of the present invention has the following features:
A support shaft 6 that rotatably supports the coating roller 3
In a roller type paint device in which one end of the handle 1 is connected to the upper end of the handle 1 arranged in a T-shape with respect to the roller 3 by a bent support rod 4, an end of the roller 3 on the side of the bent support rod 4 is provided. , an end plate 3a having a large number of locking recesses 12 on a concentric circle is provided, and a portion 4a of the bending support rod 4 extending perpendicularly from the end of the support shaft 6 is provided with When viewed from above, a lock lever 10 is pivotally supported, and the lock lever 10 can be freely fitted into and removed from the locking recess 12, which is located right next to the center of rotation of the roller 3 in the perpendicular direction, and is located parallel to the portion 4a. A feature is that an operating lever 16, which is continuously connected to the lock lever 10, is pivotally supported near the grip portion 2.

(Function) In the configuration of the present invention as described above, when the painting roller is used in a fixed manner, the lock lever is engaged with the locking recess of the end plate on the side of the painting roller, and the painting roller is fixedly used. When the roller is used in a rotatable state, the lock lever can be released from the locking recess in the end plate on the painting roller side. Switching of the lock lever can be performed by operating an operating lever near the grip. In addition, when the lock lever is engaged with the locking recess, even if rotational force is applied to the painting roller in either the forward or reverse direction, only a compressive force or a tensile force in the longitudinal direction is applied to the lock lever. Therefore, no bending force is applied.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

Reference numeral 1 is a handle provided with a grip portion 2 at one end, and reference numeral 3 is a painting roller arranged in a T-shape with respect to the handle 1. The roller 3 is rotatably supported by a support shaft 6 supported in a cantilever manner by a bending support rod 4 connected to the tip of the handle 1 via an elbow 5. 7 is a locking means, and a bracket 8 is fitted and fixed near the tip of the support rod 4;
A lock lever 10 is pivotally attached to the bracket 8 via a support shaft 9, and a spring 11 biases the lock lever 10 in the locking direction.
An end face plate 3a attached to the support rod side end of the coating roller 3 includes locking recesses 12 provided concentrically with the support shaft 6 at appropriate intervals in the circumferential direction. The lock lever 10 has a lock pin 10a at its tip that can be freely fitted into and removed from the locking recess 12, which is located directly beside the support rod 4 in the direction perpendicular to the center of rotation of the roller 3, and also It is pivotally supported by the bracket 8 in a parallel position. Reference numeral 13 denotes an operating means, which includes a bracket 14 fitted and fixed to a portion of the handle 1 adjacent to the grip portion 2;
An operating lever 16 is pivotally attached to the lever 16 via a support shaft 15, an outer wire 17 has both ends fixed to the brackets 8 and 14, and both ends are locked to the lock lever 10 and the operating lever 16. The release wire 19 includes an inner wire 18 and a release wire 19. Reference numeral 20 denotes a spring that biases the operating lever 16 in a direction that allows the lock lever 10 to swing due to the biasing force of the spring 11.
Any one of 20 can also be omitted.

Usually, the lock pin 10a of the lock lever 10
is fitted into one of the locking recesses 12 of the end plate 3a on the painting roller 3 side by the biasing force of the spring 11, so that the painting roller 3 is locked in a non-rotatable state. When switching the painting roller 3 to a rotatable state, the operator holding the grip 2 presses the operating lever 16 against the spring 20 with his or her fingertips, and moves the lock lever 10 against the spring 11 via the release wire 19. Then, the lock pin 10a at the tip can be disengaged from the locking recess 12 of the end plate 3a by swinging it outward.

Therefore, when employing a normal painting method in which the painting roller 3 is rolled on the surface to be painted during painting work, the painting roller 3 can be rotated by pressing the operating lever 16 with the fingertip as described above. If the paint roller 3 is kept in this state and a painting method similar to brush painting is to be used, the paint roller 3 can be locked by the locking means 7 by removing the fingertip from the operating lever 16 and switched to a non-rotatable state. good.
If the coating roller 3 is made unrotatable in this way, even if the handle 1 is moved to roll the roller 3 on the surface to be painted, the roller 3 will not rotate and will not rotate. The paint moves slidingly as if rubbing against it, and the painting is done in the same way as painting with a brush. At this time, the rotational force acting on the coating roller 3 is received by the lock lever 10, and the engagement position between the lock lever 10 and the coating roller 3, that is, the engagement position between the lock pin 10a and the locking recess 12. Since the lock lever 10 extends in the tangential direction, only a compressive or tensile force in the longitudinal direction acts on the lock lever 10, and almost no bending force acts on the lock lever 10.

In the embodiment, the locking means 7 is configured to continuously lock the coating roller 3 in an unrotatable state unless the operating means 13 is operated. The coating roller 3 may be held in an unlocked state, and the locking means 7 may be configured to lock the coating roller 3 by operating the operating means 13. or,
In either case, when the operating lever 16 of the operating means 13 is pressed against the spring 20, a conventionally well-known lever locking means is used to automatically lock the lever 16 in the pressed state, and the lever is continuously pressed with the fingertip. It is also possible to configure the coating roller 3 to be held in a rotatable state (or in a locked state) without continuing to press the lever 16.

The operating lever 16 may also be provided with a mechanism for selectively stabilizing the coating roller 3 in a locked position and an unlocked position.

(Effects of the invention) As described above, the roller-type paint device of the present invention can be used by selectively switching the painting roller between a rotatable state and a fixed state depending on the painting method. However, especially according to the configuration of the present invention, even if the coating roller is firmly pressed against the surface to be coated and slid with the lock lever fixed, the bending force acts on the lock lever and the roller is not deformed. There is no fear of it happening. Therefore, it is possible to use a fixing means that completely fixes the coating roller by fitting the locking pin at the end of the lock lever into the locking recess provided in the end plate on the coating roller side. This made it possible to perform painting work that was done in a fixed position reliably and efficiently.
